From d057828ee399e749d745c959eb70227bdfc7bf00 Mon Sep 17 00:00:00 2001 From: "Tim D. Smith" Date: Mon, 23 Mar 2015 23:09:57 -0700 Subject: [PATCH] Don't explicitly link Python on OS X Explicitly linking to a Python framework on OS X prevents modules from being built against one python (i.e. system python) and imported from another (i.e. Homebrew python); the interpreter segfaults if there's a linkage to a foreign python. Building the module with `-undefined dynamic_lookup` instead of an explicit link allows the symbols to be resolved at load time from a compatible python. --- modules/python/CMakeLists.txt | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/modules/python/CMakeLists.txt b/modules/python/CMakeLists.txt index 3c0f2fd..354c786 100644 --- a/modules/python/CMakeLists.txt +++ b/modules/python/CMakeLists.txt @@ -64,7 +64,11 @@ add_library(${the_module} SHARED src2/cv2.cpp ${CMAKE_CURRENT_BINARY_DIR}/genera if(PYTHON_DEBUG_LIBRARIES AND NOT PYTHON_LIBRARIES MATCHES "optimized.*debug") target_link_libraries(${the_module} debug ${PYTHON_DEBUG_LIBRARIES} optimized ${PYTHON_LIBRARIES}) else() - target_link_libraries(${the_module} ${PYTHON_LIBRARIES}) + if(APPLE) + set_target_properties(${the_module} PROPERTIES LINK_FLAGS "-undefined dynamic_lookup") + else() + target_link_libraries(${the_module} ${PYTHON_LIBRARIES}) + endif() endif() target_link_libraries(${the_module} ${OPENCV_MODULE_${the_module}_DEPS}) -- 2.7.4
